Main Specifications of SGLI

The Second-Generation Global Imager (SGLI), which is a successor of the Global Imager (GLI) aboard ADEOS-II, is an optical sensor capable of multi-channel observation at wavelengths from near-UV to the thermal infrared wavelength. (380nm to 12µm)

SGLI consists of two radiometer components, the Visible and Near Infrared Radiometer (SGLI-VNR) and the Infrared Scanner (SGLI-IRS). SGLI-VNR is capable of observing polarized and unpolarized radiances.
